Hurricane Florence wobbled closer to the coast of North Carolina on Thursday night. At 11:00 p.m. EDT on Thursday the center of Hurricane Florence was located at latitude 34.0°N and longitude 76.8°W which put it about 60 miles east-southeast of Wilmington, North Carolina. Florence was moving toward the northwest at 6 m.p.h. The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 956 mb.
A Hurricane Warning was in effect for the portion of the coast from South Santee River, South Carolina to Duck, North Carolina including Pamlico and Albemarle Sounds. A Tropical Storm Warning was in effect for the portion of the coast from Edisto Beach to South Santee River, South Carolina. A Tropical Storm Warning was also in effect for the portion of the coast from Duck, North Carolina to Cape Charles Light, Virginia and for Chesapeake Bay south of New Point Comfort.
Hurricane Florence is already affecting the coast. National Data Buoy Center C-MAN station CLKN7 at Cape Lookout, North Carolina reported a sustained wind speed of 81 m.p.h. (131 km/h) and a wind gust of 101 m.p.h. (163 km/h). Storm surges were already occurring along portions of the coast east of the center of Hurricane Florence where the winds were pushing water toward the coast. The highest surge appeared to be in the area of the western part of Pamlico Sound near the mouth of the Neuse River. There were scattered reports of wind damage and power outages.
A high pressure system over the northeastern U.S. is blocking the northward movement of Hurricane Florence. The high is steering Florence slowly toward the northwest. On its anticipated track Hurricane Florence will make a landfall near Wilmington, North Carolina on Friday. Florence could move a little south of due west after landfall. The center will pass a little north of Myrtle Beach, South Carolina and then move toward Columbia, South Carolina. Florence is likely to continue to weaken slowly. Because of the slow movement, many locations will experience extended periods of gusty winds. Power outages are likely to become more widespread on Friday. Hurricane Florence will drop locally heavy rain. Locations where rainbands are essentially station could receive over a foot (0.3 meters) of rain. Serious fresh water flooding is likely to develop on Friday and Saturday.
